Key Parameters

Substitute Part Grouping Explanation

Alternative and equivalent parts for the 2SD1758TLR are identified strictly by matching the following parameters: NPN transistor type, collector-emitter breakdown voltage equal or higher than 30 V, maximum collector current at least 2 A, maximum power dissipation up to 10 W, surface mount TO-252-3 (DPAK) package, transition frequency of at least 100MHz, and consistent compliance/certification standards (RoHS3, REACH unaffected, MSL 1). The substitute selection includes only parts within these electrical, mechanical, and compliance parameters.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute for 2SD1758TLR should be based on product status and compliance. The main component is Not For New Designs; both 2SCR572D3TL1 and ZXT849KTC are active and meet RoHS3 and REACH standards, with MSL 1 (Unlimited). These substitutes are suitable for design continuation under provided certifications and compliance requirements.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to select equivalent or substitute BJT transistors for 2SD1758TLR?
A1: Substitution is based on NPN type, collector-emitter breakdown voltage, maximum collector current, power dissipation, transition frequency, package compatibility (TO-252-3, DPAK, SC-63), and compliance certifications (RoHS3, REACH unaffected, MSL 1).

Q2: Is package compatibility mandatory for substitution?
A2: Yes, substitute transistors must share the same package and case type to maintain mechanical compatibility.

Q3: Why is the main part flagged as Not For New Designs?
A3: This indicates end-of-life or limited support, necessitating the use of active alternatives for future projects.

Q4: Are all listed substitutes compliant with international standards required for new product designs?
A4: Yes, all substitutes are ROHS3 compliant, REACH unaffected, and have MSL 1 (Unlimited), suitable for standard manufacturing processes.

Q5: Can the alternatives be used interchangeably in existing designs?
A5: Substitutes that match the key parameters and package type are suitable for direct interchange within the specified limits.
